I have been reading previous threads and it seems that brake boosters are interchangeable between the various Landcruisers up until early 1995. Is that correct? I want a new booster in my 1972 pig to go with my new FJ80 M/C from Marlin Crawler. I found a guy with a booster from a 1985 FJ60 ($150) or from a 1994 FJ80 ($225). If both will work, which one would work best? I have 4 wheel disks already on my rig and am replacing the stock booster/mc combo.
